Having the same issue on base Arch Linux with KDE and OpenJDK 8. Issue is easily reproduced by running the mouse in circles, the rotation "snaps" to a different angle at seemingly random points. Running on i7 8750H, 6GB RAM dedicated to Java and 1070 maxq.
Also, when the rotation snaps, some parts of the map in the distance seem to unload and reload, though that might just be a rendering efficiency thing.
UPDATE:
After some experimentation, the official JRE does the same thing. Also, the rotation seems to always snap towards exactly northwest (120-130 degree range). Hope this information helps.
